3 is a diagram for explaining the overall operation of a method of providing an exercise program according to an exemplary embodiment.

Referring to FIG. 3 , feedbacks 310 , 330 , and 350 that may occur in a process of providing an exercise program according to an exemplary embodiment are illustrated.

The providing apparatus according to an embodiment may provide an exercise program to the user. In this case, the provided exercise program may be generated based on personalized information or a user's exercise ability, or may be provided through a generally commercialized application. Personalization information includes, for example, the user's body information such as gender, age, height, body mass index (BMI), waist circumference, hip circumference, waist hip ratio (WHR), blood pressure, etc. may include a coefficient of physical activity of Hereinafter, a case in which each feedback occurs will be described.

The first feedback 310 may occur while the user performs an exercise according to an exercise program.

The providing apparatus according to an embodiment may provide a coaching message at regular time intervals based on a heart rate measured by the user during exercise. For example, suppose that a first coaching message or a third coaching message occurs four times in a row during the performance of the second exercise of the level 3 provided by the cycle exercise program. As described above, the first coaching message is a message for coaching to lower the pace of exercise performance, and the third coaching message is a message for coaching to increase the pace of exercise performance.

If the number of consecutively provided specific coaching messages exceeds a preset number (eg, 3 times), the providing device determines that the exercise intensity of the second exercise is not suitable for the user and adjusts the exercise intensity during the exercise. can As described above, the first feedback 310 may occur in the process of providing a coaching message at regular time intervals based on the user's heart rate measured during exercise and adjusting the exercise intensity by the number of consecutive provision of the coaching message.

The second feedback 330 may occur after the exercise program ends.

For example, after the second round of exercise of level 3 of the cycle exercise program ends, the providing device determines the message score, time score, etc. according to the heart rate measured in the second exercise, the history of providing a coaching message in the second exercise, etc. etc. can be calculated. Based on the calculated value, the providing apparatus may level up the exercise level of the exercise program to level 5, level down the exercise program to level 2, or maintain the current exercise level as it is. The second feedback 330 may be generated in the process of changing the exercise level based on a value calculated based on a heart rate, a history of providing a coaching message, and the like. According to an embodiment, in addition to changing the exercise level in the process of the second feedback 330 , the providing apparatus may change the exercise program in consideration of the user's awareness input from the user.

The third feedback 350 may be generated based on exercise history information stored in the exercise history database according to the continuous progress of the exercise program.

The providing device may change the exercise program based on the exercise effect index for each exercise, every round, every level, derived based on exercise history information according to the exercise program. The third feedback 350 may occur in the process of changing the exercise program based on the exercise effect index.

4 is a graph illustrating a change in heart rate measured by a user performing an exercise program according to an exemplary embodiment.

The graph of FIG. 4 shows the change in the user's heart rate for about 30 minutes from the time the user starts the exercise to the time the exercise ends. As can be seen from the graph, the heart rate does not immediately reach the heart rate required for exercise performance at the same time as the start of the exercise, but gradually increases for a little delay before reaching a steady state. The 'steady state' refers to a state in which the heart rate of the user gradually increases after the user starts exercising, and the heart rate is maintained almost constant without a significant change in the heart rate.

For example, when a user starts running at a speed of 8 km/h using a treadmill, the heart rate may gradually increase from 60 bpm, which is a heart rate in a rest state. The heart rate, which has gradually increased, reaches an appropriate heart rate to maintain the speed of 8 km/h, and remains constant without significant change in the subsequent time period.

The providing device may calculate various parameters related to the heart rate based on a change in the heart rate that appears during the exercise process of the user. The providing device may adjust the exercise intensity of the exercise program, change the exercise level of the exercise program, or change the exercise program itself based on the calculated parameters.

Hereinafter, various parameters shown in the graph of FIG. 4 will be described.

The measured heart rate (Real HR, or HR) represents the heart rate actually measured during the exercise process of the user.

A target heart rate (THR) is a heart rate predetermined for a user, and is a heart rate assuming a steady state when an exercise program is performed. For example, the target heart rate represents a heart rate that the user needs to achieve in a steady state in order to achieve the exercise effect suggested by the exercise program.

The providing device may determine the target heart rate of the user according to, for example, input personalization information (personal information and exercise goal, etc.). In this case, the target heart rate may be determined by, for example, Karvonen's Formula (THR = (HRmax - HRrest) x α + HRrest ) and the target strength α set by the user. HRmax (Maximum Heart Rate) is the maximum heart rate according to the age of the user recommended by the American College of Sports and Medicine (ACSM), for example, may be obtained by a formula such as (HRmax = 206.9 - 0.67 * age). In addition, α is a target intensity, that is, a measure of exercise intensity, and may have a value of 0 < α < 1 depending on the user's exercise purpose.

The resting heart rate (HRrest) represents the resting heart rate in the resting state before the user starts exercising. In the graph of FIG. 4 , the resting heart rate may be 60 bpm.

A target required HRsum (THRsum) represents an accumulated heart rate according to the target heart rate, that is, an accumulated amount of the target heart rate. The target cumulative heart rate may be an index for the sum of anaerobic and anaerobic exercise amounts according to the target heart rate. The target cumulative heart rate may be determined by, for example, a product of the target heart rate and the exercise duration as shown in Equation 1 below.

The steady state heart rate (Real HR _constant ) represents a heart rate when the measured heart rate reaches the steady state section. The steady state heart rate may be determined by the average heart rate in the steady state period.

The first accumulated heart rate (Real HRsum or HRsum) represents the accumulated sum of heart rates actually measured by the user during execution of the exercise program. The first cumulative heart rate may include an anaerobic/anaerobic metabolic portion excluding the oxygen-deprived state from the start of the exercise to the steady state before the steady state. A total amount of exercise actually performed by the user may be determined based on the first accumulated heart rate.

The first cumulative heart rate may be determined, for example, by summing all measured heart rates from the exercise start time to the exercise end time as shown in Equation 2 below.

The cumulative heart rate difference ΔHRsum represents a difference between the cumulative sum of heart rates actually measured by the user during the execution of the exercise program and the target cumulative heart rate. The cumulative heart rate difference can be used as an evaluation index of excess, maintenance, or underachievement of exercise compared to the target after exercise is finished.

The cumulative heart rate difference may be determined by, for example, a difference between the first cumulative heart rate of <Equation 2> and the target cumulative heart rate of <Equation 1> as shown in Equation 3 below.

The cumulative heart rate difference ratio (%ΔHRsum) expresses the cumulative heart rate difference as a relative value of the target cumulative heart rate, and can be used to compare the exercise effects between different exercise programs after exercise is finished.

The cumulative heart rate difference ratio may be determined, for example, by dividing the cumulative heart rate difference of <Equation 3> by the target cumulative heart rate of <Equation 1> as shown in Equation 4 below.

The second accumulated heart rate (Real required HRsum) represents a required amount of the accumulated heart rate according to the steady state heart rate when performing an actual exercise. The second cumulative heart rate may be used to determine the total of anaerobic and anaerobic exercise amounts according to the steady state heart rate. The second cumulative heart rate may be obtained by, for example, a product of a steady state heart rate and an exercise duration as shown in Equation 5 below.

Hereinafter, an example in which the providing device calculates various parameters related to the heart rate based on the heart rate information shown in the graph of FIG. 4 will be described. Here, an exercise management method when a user with a set target heart rate of 134 bpm runs will be described. It is assumed that the total exercise time presented to the user is 30 minutes, and that a steady state is reached when 5 minutes have elapsed from the start of the exercise. The providing device may calculate various parameters related to the heart rate as follows.

(1) Your target heart rate (THR): 134 bpm

(2) Target cumulative heart rate during exercise duration (THRsum)=134bpm*30min*60sec=241,200 beats

Referring to FIG. 6 , the providing apparatus according to an embodiment provides a first coaching message, a second coaching message, and a third coaching message based on a difference between a heart rate of a user performing an exercise program and a preset target heart rate and a change amount of the heart rate Any one of the coaching messages may be provided (610).

The providing device may count the number of times each of the first coaching message for coaching to lower the pace of exercise performance and the third coaching message for coaching to increase the pace of exercise performance is continuously provided ( 620 ).

The providing device may determine whether the number of times counted in step 620 exceeds a preset number (eg, three times) ( 630 ).

In step 630 , if it is determined that the counted number does not exceed a preset number, the providing apparatus may perform step 610 .

In step 630 , when it is determined that the counted number exceeds the preset number, the providing apparatus may adjust the exercise intensity of the corresponding session ( 640 ). For example, when the first coaching message is continuously provided four times, the providing device may increase the exercise intensity of the corresponding session. Also, when the third coaching message is continuously provided four times, the providing device may lower the exercise intensity of the corresponding session.

The providing device may provide an exercise program according to the exercise intensity adjusted in operation 640 ( 650 ).

7 is a view for explaining a method of providing an exercise program by feedback during exercise of the exercise program according to an exemplary embodiment.

Referring to FIG. 7 , a method for the providing apparatus to provide different coaching messages based on feedback during exercise and a method for adjusting an exercise intensity of an exercise program based on the coaching message are illustrated.

For example, the providing device may receive a target heart rate preset by an exercise program or the like, receive the heart rate measured from the user, and calculate a difference between them (β=HR THR) ( 710 ). In addition, the providing device may calculate the change amount of the heart rate (ΔHR = HR(i) - HR(i-1)) (a natural number with i≥1) ( 720 ).

The providing device may generate a coaching message based on the difference β between the heart rate and the target heart rate and the change amount ΔHR in the heart rate ( 730 ).

In step 730, the providing device first compares the difference β between the heart rate and the target heart rate with a preset threshold T _β (eg, 6 bpm), and then sets the change amount ΔHR in the heart rate to the preset threshold (T _{Δ HR} ). In this case, the threshold T _β for the difference β between the heart rate and the target heart rate may be set to the same value according to each coaching message, for example, set differently, such as T _{IP _β} T _{KP _β} T _{SD _β} it might be The threshold value T _{Δ HR} for the change amount ΔHR of the heart rate may also be set to the same value, or may be set differently, such as T _{IP_Δ HR ,} T _{KP _Δ HR ,} T _{SD _Δ HR} . .

For example, if the providing device determines that the user's heart rate at the current exercise intensity is low in light of the target heart rate (β < -6 bpm < 0), the providing device increases the current exercise intensity (Increase Pace; IP) A third coaching message for coaching may be generated.

When it is determined that the user's heart rate at the current exercise intensity is higher than the target heart rate (β > 6 bpm > 0), the providing device sends a first coaching message coaching to lower the current exercise intensity (Speed Down; SD) can create

When it is determined that the user's heart rate at the current exercise intensity is appropriate in light of the target heart rate (-6 bpm < β < 6 bpm), the providing device compares the heart rate change amount (ΔHR) with a preset threshold value (T _{△ HR} ) can

For example, when the change amount of heart rate ( _{ΔHR) < - T ΔHR ,} the providing device may generate a third coaching message for coaching to increase the current exercise intensity. Absolute value of change in heart rate (|△HR|) < T _{△ HR} If , the providing device may generate a second coaching message for coaching to keep the current exercise intensity (Keep pace; KP). Also, change in heart rate (ΔHR) > T _{△ HR} If , the providing device may generate a first coaching message for coaching to lower the current exercise intensity (SD).

The providing apparatus may adjust the exercise intensity of the exercise program according to the coaching message generated and provided in step 730 ( 750 ).

After providing the coaching message generated in step 730 to the mobile device or the wearable device, the providing apparatus may count the number of times of providing each coaching message in step 750 . The providing device may count _{the number of consecutively provided first coaching messages (SD) and third coaching messages (IP) and compare them with a preset number of times (T_CNT )} . At this time, the preset number of times (T _{_ CNT} ) is set to T _{_ SD _ CNT} for the first coaching message (SD), and may be set differently to T _{_ IP _ CNT} for the third coaching message (IP) , may be set the same.

When the number of consecutively provided first coaching messages SD exceeds the preset number T _{_ SD _ CNT} , the providing apparatus may increase the exercise intensity of the corresponding session. The providing device may increase the exercise intensity by, for example, increasing the target heart rate. This case may occur when the target heart rate THR is lower than the measured heart rate HR. For example, if the user consistently maintains a high exercise intensity despite coaching to lower the pace several times through the first coaching message SD, the providing device determines that the user's physical fitness and athletic ability are higher than the predicted level and increase the intensity of exercise.

When the number of consecutively provided third coaching messages exceeds a preset number of times (T _{_ IP _ CNT} ), the providing apparatus may lower the exercise intensity of the corresponding session. The providing device may lower the exercise intensity by, for example, lowering the target heart rate. This case may occur when the target heart rate THR is higher than the measured heart rate HR. For example, if the user continues to maintain a low exercise intensity despite coaching to increase the pace several times through the third coaching message, the providing device determines that the user's physical strength and athletic ability are lower than the predicted level, and the exercise intensity can lower

According to an exemplary embodiment, when it is determined that the exercise intensity is excessively high by more than a predetermined threshold or when the user's heart rate variation is rapidly increased, the providing apparatus may provide a warning message to the user.

A dotted line 820 indicates an upper guide line for the target heart rate of the currently executing exercise program, and a dotted line 840 indicates a lower guide line for the target heart rate. The dotted line 820 and the dotted line 840 may be determined by a threshold for a difference between the user's heart rate and the target heart rate. The dots indicated on the solid line 810 indicate the type of coaching message provided by the providing device at each corresponding time point.

The time interval 801 represents an interval in which the user's heart rate is lower than the target heart rate but the difference is not greater than the threshold, and the time interval 803 is the user's heart rate is higher than the target heart rate, but the difference is not greater than the threshold indicates the section.

The time period 805 includes a time when the user's heart rate is lower than a lower guideline for the target heart rate and a time when the user's heart rate rapidly increases by more than a predetermined standard. When the user's heart rate is lower than the lower guideline for the target heart rate in the time period 805 , the providing device provides a third coaching message coaching to increase the pace of exercise performance, and the user's heart rate rapidly increases above a certain standard When doing so, a first coaching message for coaching to lower the pace of exercise performance may be provided.

The time section 807 indicates a section in which the heart rate of the user rapidly increases up to the upper guideline and then decreases. When the heart rate of the user reaches the upper guideline in the time period 807 , the providing apparatus may provide a first coaching message for coaching to lower the exercise performance pace. Through this, the providing device can secure safety from accidents such as arrhythmias and heart attacks caused by sudden high-intensity exercise.

When it is determined that the exercise program has ended in operation 940 , the providing device may receive the user's awareness of the exercise of the corresponding session ( 950 ). Although the user's awareness is a subjective value input by the user who has performed the exercise, when statistics about this are accumulated, it may have a tendency proportional to the exercise intensity. A user's awareness (RPE) and heart rate (HR) may have a relationship such as, for example, RPE = 0.72 + 0.081*HR.

When an instruction such as increasing, maintaining, or lowering the exercise level of the exercise program is given in step 1050 , the providing device may change the exercise program by further considering the user's awareness of the result.

For example, as a result of step 1050 , when it is determined that the exercise level of the exercise program needs to be increased and the user's awareness of the exercise program is input low, the providing device may change the program to another program having a higher intensity. .

As a result of step 1050 , when it is determined that the exercise level of the exercise program should be lowered and the user's awareness of the exercise program is input to be high, the providing apparatus may change the program to another program having a lower intensity.
